Machine learning to understand fashion needs

Machine Learning is going to change fashion ecommerce, and solve real problems people have today. At Chicisimo, we use Machine Learning to help people decide what to wear, by suggesting relevant outfit ideas.

We believe that developing the correct dataset is the success factor towards building a human-level tool to offer outfit advice. And that is our focus. We are focused on understanding people’s fashion needs. What clothes someone has, what style she likes, or what she needs now. Thanks to this information, our mobile app can help people decide what to wear.

In order to have a clear understanding of needs, we have built our Social Fashion Graph. This graph gives structure to incoming data. It captures how needs, outfits and people interrelate. The Social Fashion Graph is a high-quality, well curated and growing fashion dataset, linked to a learning and training world: our app.

Our mobile app, the Social Fashion Graph, and our algorithms, are the founding patented technology assets towards our goal of automating outfit advice.

Do you want access to the Social Fashion Graph? Please email us describing your work in this space, and we’ll show you the graph. Make sure you’ve played with our iOS or Android app before.

The evolution of the music sector can explain the future of fashion

The way we enjoy our clothes and find new ones is going to change. The fundamentals of this change can be explained by looking at the music sector.

In the old days, we used radiocassettes to listen to music. We did not have an online service that could understand our taste and help us find new music. “Discovery” was limited. Years later, Audioscrobbler was born and built a mechanism for us to express our taste, by tracking the songs we played. This new data allowed product builders to create new discovery experiences, giving birth to online music as we know it today.

The songs we listen to. The clothes we wear. At Chicisimo, we love how the future looks on top of this new understanding.

We are creating a high-quality, vertical dataset, by digitizing offline data

Fashion ecommerce faces a challenge similar to music a decade ago. In order to build game-changing tools, the fashion industry needs to understand people, and not just build new algorithms. And the data required to understand people is, today, mostly offline. What I have in my closet, what I am wearing now, what my context is.

At Chicisimo, our effort consists on digitizing this data, and making it available online. Developing a high-quality dataset is the success factor towards building a human-level tool to offer outfit advice. Data is a critical element in Machine Learning for fashion.

Chicisimo is a learning mechanism. And we love how the future looks on top of this new understanding.

Building the Social Fashion Graph

We have built and patented our Social Fashion Graph to provide structure to the incoming data.

The Social Fashion Graph captures how needs, outfits and people interrelate. It is a high-quality, well curated and growing fashion dataset, linked to a learning and training world: our app.

At Chicisimo, we have built an ontology of the world’s what-to-wear needs. It summarizes and gives structure to fashion needs, as expressed by people. And our Social Fashion Graph attaches needs, to outfits and to people.

We think the ontology is pretty unique, and here is why: The traditional fashion taxonomies are a list of tags describing garment characteristics. This approach is understandable, because it is looking at clothes through the lens of other products it has worked on before (songs, books, electronics…). These other lines of products had pre-defined databases, obvious matching systems, and a type of metadata much closer to the way people describe those products.

We have learnt that fashion needs go well beyond garment-related metadata, and of course these needs are expressed in very different ways. In the age of deep learning and substancial algorithmic advances, next generation fashion taxonomies are transparent and capture the world through the eyes of people, not through the eyes of the industry.

This social, bottom-up approach contributes to smarter algorithms. It also expands the discovery experience: it empowers fashion shoppers to look at each other to decide what to wear and what to buy, instead of having to look at the traditional gatekeepers.

“I need ideas to wear this violet sweater to class tomorrow”

Did you know that most people combine violet sweaters with black pants, black boots or black blazers? Also, violet sweaters are more common during fall/winter than during spring/summer. And they tend to be worn during casual settings rather than formal.

Data is cool. But being able to recommend the right outfit for a violet sweater requires a deeper understanding of what someone likes and needs. It also requires creating the right environment for people to express their needs, where inspiration and discovery can take place.

The above is specifically what we are building.

Thanks for creating this fashion app, it helps me enjoy my clothes, great outfit planner
I love fashion, and feeling pretty makes me feel stronger. This wardrobe app helps me getting there
I totally love helping other women with my selection of fashion ideas

Product first

Product first. Building the right product experience is first for us.

It also allows us to learn what is the data that makes an impact and what is the technology that needs to be built, in order achieve our objetive of automating outfit advise.

A few examples: Thinking in terms of product and retention helps us focus on creating user habits. Thinking about the onboarding process helps us overcome the cold-start problem. Understanding product cognitive overhead, leads us to search a specific type of design.

And we love the feedback we receive, and how we are regularly featured as App of the Day by Apple in more than 60 countries in 2017, and being Android’s Best App in Spain and France 2015 and 2016.

Fashion. 10 years from now

Brands and clothes have immense meaning, because people express through them. This meaning can now be taken into account. Machine learning is the enabler, and it will change fashion ecommerce. A decade ago, we did not have Spotify. A decade from now, we will have several “Spotify for fashion”. There are some specific data-based use cases we like, that fit well together:

  • Automating outfit adviceAmazon, Alibaba, Chicisimo
  • Image understanding (Most ML efforts are here)Wide-Eyes,, ViSenze
  • Systems to match outfits and shoppable productsInstagram, Pinterest, Amazon, Chicisimo
  • Discovery of clothesAmazon, Zalando, Asos, Chicisimo
